Christ's death justifies us because it satisfied God's justice and paid the penalty for our sins (Galatians 2:21).
The justification by Christ's death is rooted in the belief that His sacrifice was sufficient to atone for our sins. Galatians 2:21 tells us, 'I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.' This verse highlights that if we could attain righteousness through the law, then Christ's death would be rendered meaningless. However, the reality is that Christ's obedience and sacrificial death secures our justification before God. He bore our sins and the curse of the law, establishing a new covenant in which we are justified by faith in Him, not by our own works (2 Corinthians 5:21).
